Quick Overview
BMS for 36V Li-ion ebike battery with countinuous discharge current being 20A. This BMS is small in dimension(L*W*H: 65*35*9mm) which you can install it into many different battery cases. If you want to make a 5V output for charging your mobile or ipad, you can add a 5V1A USB PCB when ordering the PCM.
The battery BMS has a ON/OFF switch, if you don't have swtich for your battery, you can just solder the two switch wires together.
The battery BMS also has a high temperature protection sensor; if the battery is too high in temperature, the BMS will cut off power to protect the battery.
